If you can guess what all of those have to do with numbers, you must be a regular listener.

The question of trust arises from two recent government decisions.

One is Gordon Brown's announcement that National Statistics, the agency responsible for much official data, will be made independent.

The second is the Home Secretary's creation of an all-party group to look into crime statistics.

In both cases, is there a recognition that public trust in statistics has fallen, that politicians may have played a part, and that the remedy is to put more distance between them and the figures?

Some argue that we need the same reform of official numbers as we saw when the Monetary Policy Committee was given control of Britain's interest rates.

We investigate the issues and put the various proposals for reform to a senior Labour politician.

Hedgehogs

The hedgehogs, or at least explanations for their declining squished numbers on the roads, are flourishing since our invitation last week for explanations, (unlikely explanations we readily admit) of why fewer on the roads might mean more in the wild.

And the combination of trampolines, pretty faces and the stock market will all become clear when we ask why valuations of companies can rise and fall dramatically over a short period - in the case of the FTSE 100 share index nearly halving and then doubling in the last five years.
